A tiny, fast Markdown viewer for Windows with editing, printing and PDF export. The whole app is under 2 MB and needs nothing installed — it uses the .NET Framework 4.8 and the Edge WebView2 engine already built into Windows 10/11.
- View Markdown files with GitHub-like styling: headings, lists, tables, code blocks, quotes, images (including relative paths)
- Edit in a simple Notepad-style text mode (
Ctrl+E), with unsaved-changes protection; original line endings (LF/CRLF) are preserved on save - Print to any printer with preview, or export to PDF in one click
- Open files via dialog (
Ctrl+O), drag & drop, command line (MdViewer.exe file.md) or double-click (after file association) - External links open in your default browser; links to neighbouring
.mdfiles open right in the viewer - Russian user interface
